[PATCH v6 3/4] virtio-iommu: Fix the domain_range end

From: Eric Auger
Subject: [PATCH v6 3/4] virtio-iommu: Fix the domain_range end
Date: Sat, 27 Nov 2021 08:29:09 +0100

in old times the domain range was defined by a domain_bits le32.
This was then converted into a domain_range struct. During the
upgrade the original value of '32' (bits) has been kept while
the end field now is the max value of the domain id (UINT32_MAX).
Fix that and also use UINT64_MAX for the input_range.end.
